快速成形外耳软骨支架

研究表明 ,我国外耳畸形的发病率在 1/万～ 2 /万之间。外耳畸形应在学龄前予以手术矫形 ,以免影响患者心理健康。自体肋软骨雕刻成形法存在手术创伤大、对施术者要求高和手术时间长等缺点。进口耳软骨支架造价昂贵 ,患者难以承受。根据 CT数据反求出三维实体模型 ,采用生物材料快速成形的耳软骨支架 ,不仅造型准确逼真、手术创伤小 ,而且价格低廉。 2 0世纪 90年代初期引入我国的快速成形技术结合现代生物医学技术而形成的生物材料成形技术的飞速发展 ,必然催生一种具有世界领先水平的全新产业 ,引起一场深刻的变革。这项以快速成形技术为核心的生物材料快速成形技术 ,包括了材料科学、生物医学和快速成形等技术 ,是一项多学科交叉的新技术

Rapid Manufacturing Scaffold of Auricular Cartilage for Macrotia

Investigation shows that the incidence of microtia in China is 1 to 2 per 10,000 births. Microtia should be corrected or reconstructed before school age so as to avoid the psychological impact to the patient. Reconstruction with sculpted homograft rib cartilage is of large wound, exigent of surgical technique and time consuming. The imported scaffold is too expensive for the patient. The rapid manufactured auricular scaffold with biomaterial based on the reengineered model on CT data is both exactly shaped and cheap. The rapid developing of biomaterial forming technology combining with rapid prototype technology introduced into China in 1990s and modern biomedical technology will bring about a new industry. The biomaterial rapid forming technology which involves material science, biomedicine and rapid forming technologies, is a multi subject new technology.
